Getting Married in Japan?

We at Kokusai Notary Services will help you obtain an Affidavit of Competency to Marry, quickly and easily, online.

If you are an American planning to marry in Japan, your ward office will require an Affidavit of Competency to Marry.

We prepare and notarize this document, along with the Japanese translation and supporting explanations for the ward office, entirely online from the comfort of your home.

All for a flat price of $119.00 USD.

What You Receive

You will receive everything needed for submission to a Japanese ward office (区役所 / 市役所):

1. Affidavit of Competency to Marry (English)
Prepared and notarized by an official New York Notary Public.

2. Japanese Translation
A clear Japanese translation suitable for submission to staff at the ward office.

3. Explanation Letter in Japanese
A signed document explaining online notarization for ward office staff.

4. Secure Digital Notarization Record
Your notarization includes:

  • A non-editable certified PDF

  • An editable PDF copy

  • A secure digital record of the notarization session

5. An excel sheet of ward offices that have accepted this documentation alone or not based on previous client’s experiences…. actually, as a courtesy, take a look at it right now! https://docs.google.com/spreadsheets/d/1IEa4M7mpw19XHvrgPu3p8eghpV84ly-NG6n-Yy9-qFk/edit?usp=sharing

6. A physically mailed Certificate of Authenticity with a raised seal delivered to your address, attesting to the validity of the online notarization. Japanese ward offices love a raised seal, and this dramatically changes how likely they are to accept the Affidavit of Competency to Marry without an apostille. Arrives within two weeks time.

We have a proven track record of more than 20 clients seeing success, so you don’t need to worry about traveling or navigating slow paperwork with your home state’s slow vital records office. If your local ward office additionally requests you receive an apostille for this procedure, we can schedule an appointment at the Japanese consulate in Manhattan and for an extra fee perform this on your behalf.

    “Hi Ben,

    I have been meaning to write to you and let you know that we ended up getting approved and have our marriage certificate in hand! Sorry it took me so long to let you know. We have now been in the throes of trying to get my visa updated so that I can stay in Japan. Turns out due to a newly enforced rule, I'm going to have to return to the U.S. while we submit it and wait for it to get approved. That was kind of a bummer. But we are very excited about the marriage going through!

    I can't thank you enough for your help. You were professional, responsive, and on top of it all. We are really grateful we found you. 

    Let me know the best way that I can leave a review or referral for you.”


    Cheers,

    “Hi Ben,

    Great news, we made the trip and our documentation was accepted without issue!
    It will still be some time until the Koseki is updated but for now the marriage has been accepted.

    Thank you for your fast and reliable service, you made it easy to understand the process. 

    Your knowledge of local ward preferences was invaluable in finding an office which would accept our application.

    Thanks again for all your help,”

    “Mr. Bisogno really impressed us with the speed and clarity with which he dealt with our request for an affidavit to prove marriage eligibility. Not knowing we needed this document, we were worried we would need to delay our marriage registration, but Mr. Bisogno accepted our request for the next day and sent over the necessary documents just a few hours later. He was also readily available for troubleshooting or assistance should we have any issues at the ward office, which greatly alleviated the stress we felt about getting them to approve our documents. We truly appreciate his prompt and comprehensive service, and would highly recommend him to anyone else looking to get an affidavit of single status in a rush!” - Grace on July 2, 2026

    “Hi Ben, I went back with everything today and they accepted my documents! They said they believe everything should be okay, but if there’s any issues they might call me again. It will take a few weeks to process, so we’ll see! Anyways, I think it should be good?! Thank you so much for everything!!” - Samantha in Fukuoka, July 15th 2026
